What is the instantaneous rate of change of f(x) = 4x) at x = e? 8 (Round to the nearest integersas needed.) b. The minimum of the function occurs at x = 1. The tangent line at the point x - 1 is shown. (Each tick mark on the graph 13.59 is still in steps of e.) 10.87- 8.15 The slope of the tangent line at the value of x = 1 is 5.44- 2.72- The equation of the tangent line is 0- X -2.72- 272 544 8-15 5.44- -8.15- -10.87- -13.59
